I would plan on using the server to host multiple servers.
Here are most of the servers I host:
Freebuild: Self Explanatory.
Jail Escape: You know, that game where prisoners try to escape from a jail. I recently made a new map.
The Rapist: A server I made up. There is a rapist and the other players are innocents. The innocents must try to avoid and kill the rapist. The rapist must kill all the innocents by raping them. Uses rape mod. I already have a map.
Spongebob DM: Deathmatch but with Spongebob. Currently using an edited version of the default save Afghanistan DM.
Grapple DM: Use a grapple to move around the map and backstab people with a knife. Map already made.
Gmod Murder: Like the Murder in Gmod. There are bystanders who avoid the murderer, 2 bystanders with a secret weapon who find the murderer and kill him, and the murderer has to kill everyone while trying not to get caught. Using default save for map.
Obby: If you play roblox, you will know what an obby is. An obby is an obstacle course. Map already made.
Hunger Games: When the game starts, you have to go to the warehouse and get weapons. Then, you fight each other. It's all about survival. Map already made.
Prophunt: Props disguise themselves as bricks and hide, and the hunters try to find and kill the props. Default save used.
Deathrun: The Runners have to try to get to the end and kill the Killers. The killers have to activate traps and kill the Runners. Map already made.
Boss Battles: You know, that game where the boss tries to kill all the normals and the normals have to try and kill the boss. Map already made.
There is all my uses for the server.
EDIT: Here's another server:
Hover: Like the Hover game that comes with the Windows 95 CD-ROM, you control a hovercraft and you have to collect all of the opponents flags and bring them back to your base. It's like a basic CTF but with hovercrafts. There will also be power-ups and power-downs that will activate immediately after getting one. Powerups are on Squares placed around the map. Map made recently.
EDIT 2: Made a new server:
Elevator VS Zombies: You can play as either the Civilians, the Zombies, a Guard, or a Janitor. The Civilians have no weapons and stay in the elevator, the janitor has a push room to push the zombies away, the guard has a 50 HP shield and revolver to kill the zombies, and the zombies try to kill everyone. Everyone has only 1 life. Map made recently.
